I THANK PRESIDENT BARRACK H OBAMA -this good and great human- and outstanding President and Leader.

And I thank all the leaders of the free world, just as I thank all the students of the *United States of America*, for their sterling *sense and sensibilities* on Sam Daily Times : '' the voice of the voiceless'' -the world over, and on !WOW! and !E-WOW!.

Ever so often, these very days, the Pakistani newspapers display the photos of the Pakistani students on ''cross training'' in America, and Europe, too.

Warms the heart, as I thank Ambassador David Hale, and all the mission staff.

And with Ambassador Hale, at the first convenient honour I get, I will seek a formal meeting to discuss matters of mutual interest.

*PRIMED PEER-TO-PEER* with an elegant algorithm of C++, I zoom into TOR, to watch the first *Campside Fire Log* of the distinguished

IN 1543 - Nicolaus Copernicus proposed, in a mathematically rigorous way, that the Earth is not centre of the universe, and thus that all things do not resolve around it.

In fact, only the Moon does so. Seven decades later Galileo Galilei provided more direct proof of Earth's lack of specialness. He looked at Jupiter through a primitive telescope and found that the planet had four moons of its own.

Four centuries after Galileo's discovery, it remains impossible to understand the solar system without understanding Jupiter. The sun accounts for 99.8% of the Solar System's mass.

But Jupiter, which is more than twice as massive as the other seven planets put together, makes up most of the rest.

Its heft shapes up the orbits of the other planets, the structure of the asteroid belt and and the periods of many comets. And the four moons observed by Galileo, have proved merely the biggest members of an entire solar system in miniature; at the moment Jupiter has 67 known satellites.

One picture taken on June 21st by Juno, a probe belonging to NASA, America's space agency, that is named after the Roman goddess, who was both Jupiter's wife and sister.

If all goes well and according to plan, and it did, Juno became a 68th satellite of Jupiter on July 4, arriving almost five years after it was launched. Though Jupiter has had other man made visitors, all but one of them simply flew past it on their way elsewhere-

Taking a few photographs to send back home while they gathered energy from the Jovian gravitational field in a so called slingshot manoeuvre, to speed their journeys up.

Only Galileo, which arrived in 1995, has previously gone into orbit around the place.

Dancing with death: Doing so is a risky business, Juno, which is at the moment, moving in around 250,000 kilometres an hour, is one of the fastest man-made objects ever built.

When it arrives its guidance computer will have just over 30 minutes to slow the craft down and thread into a series of long, looping orbits that will cause it to swoop to within 4,500 km of the top's of Jupiter clouds and then zoom out again to a distance of more than 2.5 million km.

If anything goes wrong during this deceleration, the probe will have to fix the problem itself. Assistance from Earth will be impossible, for radio signals from mission control in California take nearly an hour to reach.

Yet a fix may be needed. Jupiter is a hostile place. Its enormous magnetic field traps and accelerates high-energy particles [mostly protons and electrons] thrown off by the sun. That gives it the fiercest radiation belts of any planet in the solar system.

Such radiation plays havoc with electronics. Galileo suffered more than 20 radiation related glitches over the course of its eight year mission.

These included resets of the main computer, glitches in ts cameras and problems with the radio.

Juno's electronics are protected by a 200kg titanium vault that has walls a centimetre thick. Its looping orbits are designed to minimise the time it spends in the most radioacrive zones.

Even so, the radiation will take its toll.

The Honour and Serving of the *Advance Space Technologies* operational research continues. Thank Ya all for reading and sharing forward, and see you on the delightful next one that follows.

With respectful dedication to the Students, professors and Teachers of the World. See Ya all on !WOW! -the World Students Society and !E-WOW! -the Ecosystem 2011:
